Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Integrated Dust Extraction with Dust Box
(see figures C1–C4)
Attach the dust box 3 onto the extraction outlet

The filling level of the dust box 3 can easily be
checked through the transparent container.
To empty the dust box 3, pull it off downward
with a light twisting motion.
Before opening the dust box 3, it is recommend-
ed to loosen the dust from the filter element by
gently striking it against a firm support (as
shown in the figure).
Hold the dust box 3 firmly, fold the filter element
8 upward and empty the dust box. Clean the thin
plates of the filter element 8 with a soft brush.
External Dust Extraction (see figure D)
Attach a vacuum hose 9 onto the outlet piece 7.
Connect the vacuum hose 9 with a vacuum
cleaner. An overview for connecting to various
vacuum cleaners can be found at the beginning
of these operating instructions.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
